22、 125 A, intended for household and similar fixed installation including residential, commercial and light industrial buildings. This standard also applies to “plug-in filters“. These filters (see Figure 1) are used to set a suitable impedance, in the nominal frequency range of the mains signalling s
23、ystem, at any point of the low voltage mains network where a low impedance equipment is connected, in order to allow reliable operation of mains signalling system. These impedance filters can be used either in utility or consumer networks. They may also be used in conjunction with incoming filters a

34、filter shall have a network port connected to the mains communication network and an equipment port connected to either a low impedance equipment or a low impedance network. Implementation of impedance filter may not distinguish both ports when designed symmetrically. 4.2 Operating frequency range T
35、he operating frequency range is a (reduced) frequency range the filter is designed for. It shall be in the frequency band 3 kHz to 95 kHz for the utility network, It shall be in the frequency band 95 kHz to 148,5 kHz for the consumer network.

36、 when measured in the operating frequency range in accordance with 6.1 of EN 50065-4-1, the filter shall have a minimum impedance modulus value of 10 . At the equipment port there is no impedance requirement. NOTE When used in conjunction with an incoming filter type 3 (at the utility side), the com
